SPINN ING-MACHIN E.

inedita.

To all whom t may concern:

)e it known that I, GEORGE L. RICE, a

. citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Spinningdvlachines, of which the following is a full, clear, and eX- act specification.

his invention relates chinos for producing binder twine.

The roving gill type of spinning machine has been used many years for the spinning of soft and short fibers for commercial yarn. The roving gill spinner also has been used for spinning hard7 coarse fibers into asingle strand yarn, such as binder twine. The binder twine produced by tiis machine, while being even, is left in a rough and unfinished condition. A rough, unfinished twine is objectionable in many cases.

To obtain the best commercial results, binder twine should present a hard, smooth and glossy finish in addition to being even throughout its length.

lt, therefore, is the main object of my invention to produce twine which, when spun, is notv only even throughout its length, but at the same time has a hard, smooth and glossy finish.

This object is accomplished by providing and equipping a spinning machine with cooperating parts for producing twine adapted to meet all commercial requirenu-mts.

The invention is illustrated on the accompanying sheets of drawings, in which- Figure 1 is a fragmentary side elevation, parts being in section, of a spinningmachine of the roving gill type embodying' my invention;

upper nipper and smoothing dies against their lower coperating dies; and

Fig. 6 is a detail sectional view showing a frictional driving connection between the driving source and bobbin supporting member.

The various novel features of my invention will be apparent from the following description and drawings, and will be particularly pointed out in the appended claims.

ln the regular roving frame the liber is drawn by the roller and twisted into twine between the flier and the roller, the twist in all cases being stopped by the drawing roller. I am well aware that there have been many .attempts to put on a smoother in the space between roller, but these were simply for the pui'- pose of smoothing the twine after it was prevent the twist from running back to the drawing roller.

In my arrangement the nipper is installed between the flier and the drawing roller, and the twine is formed between the flier and the nipper, the function of the drawing roller being' to deliver the fiber in an unstate to the nipper, where the twine is made. To accomplish this it is necessary that at no time there should be suiiicient strain on the liber between the liier and nipper to cause the twist to pass through the nipper to the roller, and this is accomplished by means of a tension on the bobbin drive, which makes the surface speed of the bobbin travel a little slower at all times than is necessary to take up the amount of twine fed by the drawing roller, and any time too much slack accumulates between the nipper and the drawing roller, the bobbins will increase in speed until the excess slack is taken up, which keeps practically a uniform pull on the twine at all times; Without some flexibility at this point it would be impossible to accomplish this.

With this understanding, attention is directed to the drawings, in which it willbe noted that my invention is shown in connection with a spinning machine 10 of the roving gill type, having a frame 11, in which is mounted a driving gear 12, from which, through suitable gears 13, 14 and 15, the roll 16 of the machine is driven. Fiber, in theformof a sliver 17, is fed between the roll U16-andthe cooperating-rolls 18by the usual and 18 to the fliers 23 -onto bobbins 24, .which are the fiiers 23, a series point 31 of the nipper dies toothed chain 19, suitable manner.

mounted to a frame member 22, the rolls .18

pressing' against the roll 116 under the influence of their own weight.

lHeretofore it has been customaryT to pass the sliver'directly from between the rolls 16 for winding the twine rotated in the same direction lwith the Hiers 23 but at a slower speed than said fliers. While it has been possible to spin a twine even throughout its length with this arrangement, it has not been possible to give the twine a smooth, hard, glossy finish, which is not only desirable, but is absolutely necessary to give the best commercial results. To produce a twine which is not onlyevcn throughout its length, but also which has a smooth, hard and glossy finish, I have provided in this spinning machine, intermediate the rollers 16 and 18 and of finishing members 25, which members are secured to a suitable 'transversely arranged support 26, said members being staggered thereon crosswise of the machine.

Each of these finishing members `includes a condenser 27, upper and lower nipper dies 28, and upper and lower smoothing dies 29,

lthe condenser in each case being adjacent Vthe cooperating rollers 16 and 1S to receive the sliver passing therefrom. From the con denser the sliver is passed between lthe nip per dies 28, where the sliver is pinched for the purpose of spinning the sliver into twine,

through the laction of the fliers 23, the twist in the twine extending back to the nippel-s and no farther. VFrom the nipper dies 28-tlie twine passes through the smoothing dies 29, where thetwine is given a hard, smooth and glossyV finish, and passes therefrom in the form of twine B0 to the fliers 23, from which it iswound into the bobbins 24.

It is to be noted, reference being had to Fig. 4 of the drawings, that thesliver continues to L1be such up to and including the 28, where the sliver vis pinched, thus preventing the twist 'in the twine fr in .extending farther backward toward the rollers 16 and 18. In other words, the sliver is twisted into twine at the point 3 1 of the nipper dies, the twine thus twisted ybeing smoothed in the smoothing dies 29. Tere it not 'for the fact that the nipper dies arelocated adjacent the smoothing dies and intermediate the smoothing dies and the rollers v16 Aand 18, the twist in the twine would extend way back to said `rollers and the twine'thus produced would not and VBS acting to ytive positions.

finishing members .25 `to Vswinging .could not be as smooth as the twine pro-V tained in yieldable contact with the lower nipper and smoothing dies, respectively, by springpressed plungers 32, (see Fig. 5) which are mounted in Vthreaded receptacles .33, the Ilatter'being adjustably mounted in an arm 34 pivotally mounted at 35 to the main supporting portion :36 :of the finishing members 25. The plungers 32fliave a stem 36a which passes through anopeningin the upper part ofthe receptacle 83 and is limited `in its downwardmoif'ement-by any suitable keyfor pin 37. Ey means of thesprings force the plungers 32 against the upper nipper and smoothing dies, said dies are held in yieldable engagementwith their cooperating lowernipper and smooth;

ing dies. To lock the arm 34 in proper posit-ion to cause the full force ofthe. springs 38 to be exerted against the plungers 32 for holding the 4saine against the upper nipper and smoothing dies, I have provided a pirotal latch 39 which passes over aprojection 40 of the arm 34 for the desiredV purpose, said latch having a hollow port-ion 41 in which is mounted a spring 42 forholding the latch in locking position. lVhen they latch 39 is withdrawn from lthe projection 40 of arm 34 against the-tension of its. spring 42, the arm 34, with its springpressed plunger, may be swung out ofengagemeiit with the upper nipper and smoothing dies. Y

To place thebobbins properly inthe machinev and to perinitthe same tobe removed therefrom, it is necessary toinove the finishoutof their normal operavTo accomplish this l have the support v26 Afor the oneend of arms 43, the other end of said arms being pivotally mounted to a shaft 44 upon which :the rollers 18are mounted. Intermediate the ends of the arms 43 on each side of the machine is pivotally connected a vlink L45,fin turn pivotallyconnected to an arm `46, which 'is integral with an arm 47 pivotally Vmounted upon a rod 48, theaim47 'liavingat its end a weight 49. Byineans ofthis arrangement it is seen `that the finishing ineinbers'may be swung out of the .path of movement of the bobbins 24, when they are being placed in and removed `from the machine, .the movement being transmitted through the arms 43,"linlr 145 and arm .46, which latter arm is connected to rod '48 mounted in the frame support 22, the weight ing members 25 49 counterbalancing the weight of the tinishing members 26 in their raised position. The fliers 23, which are mounted upon vendsfwhich mesh" withanitegrally `formed -spur and bevelY `and secured to neither gear 52, the "bevel gear portion meshing with another bevel gear 53,

-whi^ch"receives its motion `'freni the driving and 57,the"gears 55 and upon 'the same shaft58. The gears are`so Vproportioned that theffliers 23 rotate at a greater speed than the vbobbins 24, the bobbins" `being driven Afrom gear 55 through with gears 64," each of which (see Fig.6) is"formed on a sleeve which loosely surrounds the'spindl'e 50. In each case, keyed to the sleeves65 to rotate therewith, is a Adisk 66, which is separated from the bobbin ,carryingl disk 67 loosely mounted on sleeve 65 by a circular disk of friction material 68, such as leather "or any other suitable material, this friction disk being preferably simply placed between the disks 66 and 67 one, this disk 68 forming a slip or friction drive between the source of driving power and the bobbin 24E, which ismounted upon the disk 67. The bobbin 24 is held upon the disk 67 in the usual way by the heads 69 of studs passing `up into openings in the bobbin forthereception ofsaid heads, whereby rotary movement is transmitted to the bobbin. The disk 66, which is keyed to thesleeve 65, is pressed toward the disk 67 and yieldingly held in engagement with the intermediate friction disk 68 by a flat 7 O which engages a grooved portion in the disk 66 and rests against a suitablypadded shoulder portion 7l on the sleeve 65. `By means of this slip arrangement there ma be a relative motion between the disks 66 and 67 to give the bobbin an increased speed' to accommodate the more rapidly moving flier 23 under lextreme conditions.

The nippers 28 having upon the sliver for determining the point of twist in the twine necessarily tend to hold the twine against the forward pulling movement of the iiers, which latter wind the twine on the bobbins. The fliers 23, however, are driven at a definite and relatively fixed velocity, thus drawing the twine from the nippers at a relatively high speed regardless of the twine. In view of the fact that the fliers 23 rotate at a speed considerably in excess of that of the bobbins 24, it is apparent that there is a great tension in the twine between the fliers and bobbins. The strain in the twine between the fliers and bobbins might be so great as to cause a break in the twine. This would be the case were it not for the slip or friction connection between the disks 66 and 67, or between the driving source for "an increased' speed to more nearly approach Aand falling of the bobbin support and still spirally arranged springV a pinching effect strains placed on the th'ebo'bbins" and the bobbins proper. `In other words, when the tensionin the twine becomes-sufiiciently great between the fliers and bobbins, the bobbins 24 will be given 70 the speed of the `fliers andthereby decrease `or entirely release the extra strainplaced upon" the twine between the pointsin question.` As stated above, this is madepossible by means ofthe slip connection between the disks 6614 and 67. This is of prime importance, especially where nippers are used for pinching the sliver Aand thus holding the twine to aA greater extent against the action of the `iiiers.

\ The Vbobbins are given the usual reciprocatory motion for distributing the turns of twine on the bobbins, the reciprocatory action being transmitted to the bobbin sup-1 porting table 72, which is formed integral 'with a sleeve 73 slidably mounted upon a suitable vertically arranged stationary support`7ll. This sleeve 7 3 is provided with `a rack 75, which is engaged bya pinion 76 which receives its forward and reverse motion from any `suitable source. It will be notedthat the gears 55, 59 and 60 are so arranged in the usual manner by pivotaklly mounted links.77 and 7S to permit a rising keep in mesh to transmit rotary motion `to the bobbins. i

equipping this roving gill spinning machine with finishing means including the condenser 27, coperating nipper dies 28, and coperating smoothing dies 29, all intermediate the rolls 16 and 18 of the machine and the fliers 23, twine is produced which not only is even throughout its length, but which is given a smooth, hard and glossy finish which heretofore has not been accomplished by a machine of 'this type. By means of the slip connection between the bobbins and their driving source, undue tension in the twine which might cause a breaking thereof is obviated; in other words, the slip connection permits the bobbins to take on an increased speed to more nearly approach the speed of the iiiers under the direct influence of the iiiers, which transmits the excess speed to the bobbins through twine placed under eX- cess tension. By means of the arrangement of the nipper and smoothing dies having spring-pressed plungers for pressing the upper dies in contact with the lower dies and a. spring-pressed latch for holding said plungers in engagement with the upper dies, the sliver may be properly gripped at the nipper dies to form a proper point of twist and to prevent the twist from running way back to the rollers, and atthe same `time to give the twine a smooth, hard and glossy finish. Again, these finishing members, in-

which are staggered along the transversely arranged support 26, may be swung out of their normal position and counterbalanced by the weighted arm 47 to permit the bobbins to be placed on and removed readily from the bobbin supports.

It is evident that there may be many modifications in the precise arrangement as herein particularly shown and described, and it is my intention to cover all such modifications which do not involve a departure from the spirit and scope of' my invention.

What I claim as new is:

1. In a twine spinning machine, the combination of an adjustably mounted nipper, means for positively feeding to said nipper a sliver of fiber of the proper size to produce twine of a desired tensile strength, and means for pulling the sliver through the nipper when in one position and twisting it into twine after it passes through the nipper.

2. In a spinning machine, coperating rollers between-which a sliver passes, a flier, and pivotally mounted finishing means comprising a nipper and polisher interposed be tween said rollers and flier.

3. In a spinning machine, coperating rollers between which a sliver passes, aflier, pivotally mounted finishing means comprising a nipper and polisher interposed between said rollers and flier, and means for Counterbalancing said finishing means when swung from its normal position.
